From the Book of Commandments written by Zhuge Liang in Han Dynasty: A husband must be quiet before learning; If he doesn't learn, he won't learn widely; If he is not determined, he will not succeed. If you are slow, you can't be energetic, and if you are dangerous, you can't be radical.

It means: learning must be calm and single-minded, and talent comes from hard work. If you don't study, you can't grow your talents. If you don't have a clear ambition, you can't achieve something in your studies. Indulge in debauchery, passive neglect, can not promote the soul to refresh the spirit, rush to take risks, impatience, can not cultivate temperament.

Background:

This article was written in 234 AD (the 12th year of Jian Xing in Shu Han Dynasty), and it was a letter from Zhuge Liang to his eight-year-old son Zhuge Zhan. Zhuge Liang dedicated his life to the country and died. He worked day and night for the national cause of Shu and Han and neglected to educate his son personally, so he wrote this letter to warn Zhuge Zhan.
